BELT-WINDER FOR THRESHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 637,760, dated November 28, 1899. Application filed June 6,1896. Serial No. 594,582. (No model.)

To all whom it may concern:

Be it known that I, JOHN B. BARTHOLOMEW, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Belt-Winders for Threshing-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a section of a sufficient portion of a thresher to illustrate the manner of applying my invention. Fig. 2 is a side elevation of the winding device. Fig. 3 illustrates the manner of connecting the belt when the winding commences. Fig. 4 is a section of the parts in Fig. 3. Fig. 5 shows the belt in position after winding. Fig. 6 is a section through the guide'roller and vertical arm.

In the drawings, A represents a part of the frames and casing of a thresher at the cylinder end of the machine. The cylinders of these machines are driven by steam engines or horse-power from which the power is transmitted by long belts to the pulleys of the cylinders. During transportation or when a machine is out of use its belt must be packed in such manner as to occupy little room.

The object of this invention is to provide a winder or reelby which the belt shall be wound uniformly on the several sides of the axis of winding, so that it can be much more easily manipulated than can any of those with which I am acquainted.

I provide a frame B, adapted to be readily attached to the thresher-frame at a point suitably near the cylinder. As shown, it consists, mainly, of a bar bent to have the vertical arm I), the top part b, witha foot-piece b the bottom part 12 and the short upwardly-extended arm 19 having a foot-piece 6 The foot-pieces b and b are bolted to the thresher-frame.

0 represents the main part of the winding shaft or reel. At its ends it has trunnions or reel-frame.

to the axis of the journals, and on the opposite side of the axis there are two winding arms D. These arms are relatively short inwardly-turned studs lying substantially parallel to the part 0. The journal 0 is extended outward far enough to receive the crank E, by which the winder can be readily rotated.

The manner of using the device will be readily understood. When the belt is removed from the cylinder and engine, it is first looped, as shown in Figs. 3 and 4, and one flap of it is crimped slightly, so that its edges can be slipped outward under the hook-like arms D. Then the loop of the belt is held, so that when the part C is rotated by the crank E the belt is coiled around the axis till it is wrapped solid, as shown in Fig. 5.

With the journal 0 a locking-ratchet can be combined to hold the reel in any desired position.

I am aware of the fact that belt-winders have been heretofore constructed, but in each of those within my knowledge the shaft of the reel was at the axis and extended continuously across the device, the winding-pins be ing arranged to revolve around the axial shaft. In such constructions the belt is not wound uniformly as to the axis of rotation. It is difficult to have a sharp flat bend at the initial loop, as these belts are made of thick refractory leather. The loop at the bend is on long radii, and when all the slack or loose portion is on one side of the axis of winding the general coil-helix that is formed is eccentric and grows increasingly heavier upon one side or the other, often making it quite diffi cult to effect the wrapping.

In the present construction the stifi looped part of the belt is distributed uniformly across the axis of winding because of the two beltsupports, the bar 0 and the pins or lugs D D being both eccentric and equidistant from the axis. Consequently the whole mass of the coil or helix is wound uniformly around this axis, the operator has no weight to lift at any particular part of the revolution,and the wrap ping can be compactly effected.

F is a long vertically-arranged guide-roller mounted in clips or short arms ff, secured to the outer part of the frame, and it extends from the axis of winding upward over the entire completed coil of the belt, so as to be adapted to engage with the edge of the latbar being eccentric to the axis of winding and ter up to the last coil and guide it. To avoid substantially equidistant therefrom, substanhaving an unduly long roller, it can be terti a11y as set forth. minated a short distance below the axis, as In testimony whereof I affix my signature 5 shwlrlnt I, 1 in presence of two witnesses.
